Patented June 10, 1930 UNITED 'STATES PATENT oFF/ica JOHN B. VAN WORKER,OF TOLEDO, OHIO, ASSIGNOR TO THE AMERICAN PAPER BOT- TLE COMPANY, OFTOLEDO, OHIO, A CORPORATION OF OHIO rma-Box sEaLINe Application med Hay14, 1928. Serial No. 277,415.

This invention relates to containers, especially of sheet material.

This invention has utility as a single service receptacle for liquids asmilk.

Referring to the drawings Fig. 1 is a .perspective view, with partsbroken away, of an` embodiment of the invention as a milk bottle orcontainer;

Fig. l2 is a view of the closure for the container of Fig. 1 in openposition;

Fig. 3 is a fragmentary view of the container closure with thetuck-in-tongue so assembled, with the supplemental wrapper not bent oversuch tongue as yet;

Fig. 4 is a sectlon on an enlarged scale on the line IV-IV, Fig. 1; and

Fig. 5 is a view of the blank for the container of Fig. 1.

In the instance shown, sheet stock as paper may be taken in providing`blank having container sides 1, 2, 3, 4, with connecting ap 5 thereforto form such into a tube. Bottom 6 is supported by bottom sections 7, 8,with outer bottom seat 9 therefor. This carton blank or container isdesirably of waterproofed or parailin-coated stock, when the substanceto be carried is a liquid as milk. The substance of the container 1sessentially one which is not soluble by the contents at normaltemperatures. This closed end tube is provided with top closureincluding opposing rectangular sections 10, 11, intermediate triangularmajor sections 12, 13, having connecting triangular portions 14. Therectangular sections 10, 11, are approximately of half closure extent,and thus'similar to the bottom sections 7', 8. Continuous beyond thisseries of rectangular sections 10, 11, and trif angular sections 12, 13,14, is extension band 15. This band 15 has beyond the rectangular-section 10, tuck-in-tongue extension 16, and

' Abeyond the rectangular section 11, supplemental flap 17 terminatingin wings 18 as a wrapper.

In the use of this container, it-may be set up as to closin either topor bottom before charging with t e contents. In the event the top isrst'closed, the bottom is sealed thereon, while in the event the bottomclosure be the one rst sealed, then the top closure is the one to besealed thereafter when the container is charged with its contents say ofmilk. In the instance the bottom closure be first sealed, the sealingmay be supplemented by a paraiin coat, or the container be given aninltial paralin coating. As thus sealed in assembly with the insolublecoating as to the contents, the top closure as a tube extension with theband 15 continuous, may be opened to receive the charge of milk say aspre-measured in a machine. The tubular extension top closure is thencollapsed, which collapse is initially as shown in Fig. 2. Furtherprogress of this collapsing permits insertion of the tongue 16 back ofthe band portion 15 as,

adjacent the triangular sections 14 and with the tongue adjacent theband portion as above the rectangular section 11.

In practice, aimost effective double sealing is obtained under theinvention herein by dipping the tongue 16 and supplemental flaps 17, 18,or even up to the band 15 in the coating material just prior to thecharge of the milk into this container. Accordingly, with this coatino'adherent but not fully set, the insertion of the tongue 16 between thefolded band portion above the section 14 and adjacent the band portionabove the section 11 brings about a cohesion between these sections andthe tongue which is a primary sealing to be supplemented by foldin overof the supplemental flap 17 to be adjacent the band portion 15 ascarrying the tongue 16,. Thereafter the supplemental ila 18 may bewrapped to the o posite side o this rojecting reinforcing ri of theclosure to e adjacent the band 15 as above the section 11 and mountingthis supplemental flap or wrap er 17. Accordingly the fold over of thisl)ap 17 is the supplemental sealing with the flap extension 18 coactingas adhering against the band 15 for locking the wrapper in thesupplemental sealing assembly.

This doubly sealed rib closure container in ltself to have a relia leseal reinforcement against fracture and of such stability that the ribma serve as a handle. In packing or nesting t ese containers, there isthus clearance provision therebetween allowing for temperature expansiondisturbermits the i ances as avoiding rupture of the containers. Inractice, the container may be opened by j ab ing a tool therethrough.

What is claimed and it is desired to secure by Letters Patent is:

A container comprising an end closure, aV

pair of opposing rectangularly defined sections, connectingintermediately triangularly defined sections, said rectangular andtriangular sections terminating in a continuous band extension withadditional supplemental extensions beyond said band for the rectangularsections, the band portions intermediate the rectangular sections beingfoldablebetween the band portions at the rectangular sections, one ofsaid suplef` -1nmental extensions vcoacting as a tuc tongue from itsrectangular section band portion over the folded band portions from theintermediate sections in a container closure rib-forming assembly andthe other extension from its band portion foldable over thetuck-in-tongue and against the band portion for said tongue coacting asaseal thereover, and additional sealing effecting holding means coactingbetween the opposing portions of the continuous band.

In Witness whereof I aHX my signature.
